I am running a simple wasmJs app from my server but get the following error
Copy code
NotImplementedError: An operation is not implemented: Not yet implemented composeApp.js:2:198840
... (Details in thread)
Can anybody tell me how to read that output and make any sense out of it? What is not implemented and where was it used?
I replaced the real URL with my URL here.

It looks a lot like some TODO() fail with a default message. I see no source locations in your stack trace, are you running a “production” version? Perhaps, a “development” build would show the place of the exception thrown.

Ahh, that’s a good advice. I’ll try with a dev version and see what the difference is.
By using a dev version the output looks more readable but I still don’t have a clue what actually went wrong.

You were right. With a few old-style log-statements I found the location where I used a 
TODO("Not yet implemented")
. I now added a proper location information manually to the message. On other platforms you get that information automatically. Many thanks again for the hint.
